This thesis aims to describe the importance of the evaluation of Quality of Service (QoS) for Web Services. Web Services are an increasingly important technology and it is important to describe a way by which we can monitor the Quality of Service. After describing what Web Services are and their importance in Service-Oriented Architectures we will examine in detail the most relevant aspects of QoS. We will deal with some methods to extend the quality description of a service in order to facilitate the discovery of a service. Finally, we will describe an algorithm in the literature to control the quality of services and we will apply it to compare the trend of QoS among different services.
Questo lavoro si pone l’obbiettivo di sottolineare l’importanza della valutazione della “Quality of Service (QoS)” di un Web Service. I Web Service sono una tecnologia sempre più importante ed è dunque importante descrivere una modalità attraverso la quale poterne monitorare la QoS. Dopo aver descritto cosa sono i Web Service e la loro importanza in Architetture Service-Oriented (SOA), esamineremo in dettaglio gli aspetti più rilevanti della QoS. Tratteremo un metodo per estendere la descrizione di un servizio in modo da facilitarne la ricerca all’interno di un registro. Infine, descriveremo un algoritmo, trovato in letteratura, per controllare la qualità dei servizi e lo applicheremo per paragonare l’andamento della QoS tra diversi servizi.

Abstract
This thesis aims to describe the importance of the evaluation of Quality of Service (QoS) for Web Services. Web Services are an increasingly important technology and it is important to describe a way by which we can monitor the Quality of Service. After describing what Web Services are and their importance in Service-Oriented Architectures we will examine in detail the most relevant aspects of QoS. We will deal with some methods to extend the quality description of a service in order to facilitate the discovery of a service. Finally, we will describe an algorithm in the literature to control the quality of services and we will apply it to compare the trend of QoS among different services.File | Dimensione | Formato | |
